CARTRlDGE-EJECTOR FOR BREAKDOWN GUNS.

SPECIFICATION forming part of Letters Patent No. 754,092, dated March 8, 1904. Application filed July 8, 1902. Serial No. 114,737. (No model.)

To all whom, it nury concern:

Be it known that I, Orro W. Rmcovrsr, a citizen of the UnitedStates, residing at Fitchburg, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in Cartridge- Ejectors for Breakdown Guns, of which the following is a specification, accompanied by drawings forming a part of the same, in which- Figure 1 is a view in side elevation of a portion of a breakdown gun, showing it in its normal position, a portion of the frame being broken away to display the interior mechanism. Fig. 2 is a longitudinal sectional view of the same portion of the gun, showing it broken down. 'Fig. 3 is a transverse vertical section on the line 3 3, Fig. 1, looking toward the gun-stock. Fig. 4 is a transverse vertical section on the line 4 1, Fig. 2, looking toward the muzzle of the gun; and Fig. 5 is a detached view in perspective of the block in which the catch is pivoted.

Similar reference characters refer to certain parts in the difierent views.

The object of this invention is to provide means for automatically locking and releasing the cartridge-ejector, the locking being efi'ected simultaneously with the closing of the gun and the release when ithas been opened a predetermined distance; andthe invention consists, mainly, in a spring-actuated catch disposed transversely of the gun and barrel, in proximity to the ejector, in position to engage the ejector when the latter is forced forwardly, and provided with a toe in position to strike a shoulder on the gun-frame, whereby the catch is withdrawn from the ejector and the latter is given freedom to slide rearward in response to its spring actuation, thus causing the forcible ejection of the cartridge from the gun-barrel.

In the accompanying drawings, 1 represents the gun-frame of the gun'; 2, the barrel; 3, a rib on its lower side, and4= is the usual hingepin for connecting the frame and barrel.

The numeral 5 indicates the ejector, which is fitted to a bore 6, formed at the junction of the barrel and barrel-rib, and a moderatelystifi spiral spring 7 in the inner end of the bore 5 6 expands against the ejector to throw the latter forcibly rearward when not otherwise hindered by other parts of my invention. The extreme rear end of the ejector is provided. with a notch 8, in which the flange of. the cartridge is 5 seated, and the rounded portion 9 of the ejector is constructed and adapted to sweep against -the upright face 10 of the frame inclosing the gun, whereby the ejector is forced forward, with its cartridge, to the position shown in Fig. 1 of the drawings. The longitudinal movement of the ejector is limited to the length of a notch 11 in its lower side, and the end of a screw12, protruding therein, affords a stop.

The ejector'is automatically locked and released by the following mechanism: An opening 13 is cut transversely through the rib at a point at or near its center, and in this opening 13 a block 14. is fitted. This block is recessed across the top and down one side. thereby subdividing it into two parts, which parts are connected by the solid portion 16. Confined between the vertical walls 17 17 thus formed is a catch 18, which is pivoted by means of a pin 19, located at one side. As this catch just fits between the vertical walls 17 17 lateral play is prevented, while it is given freedom of motion up and down upon its pivot 19. It is important that lateral play be thus resisted. because the catch must operate in opposition to the expansive force of the spring 7.. The catch 18 is provided at its top with a lip 20, the rear edge 21 of which is slightly beveled, and this lip is adapted to enter a notch 22 in the lower side of the ejector when the latter is pushed forward against the action of the spring 7, and to insure this action a spring 23 is interposed between the solid portion 16 of the block and the lower side of the catch. From the foregoing it will be seen that when the for ward edge of the notch 22 shall have cleared the lip 21 said lip will spring into the notch and lock the ejector in position.

Asia simple means for disengaging or releasing the ejector when the gun is broken down the following mechanism is employed:

formed in the inner face of the n, and in it the too of the said toe normally being at the the cavity in position to be shoulder 26 at the top of the the gun shall have been comn down. The upper edge of :htly beveled, as at 27, so as to uately flat upon this shoulder is opened. To afiord clearance assembling the parts of the gun, formed vertically from the cavipper surface of the gun-frame, iting the barrel with the gun is swung downward through and thence forced rearward :avity 24: until the holes in the lbarrel which receive the hinge- .to alinement with each other. i this cavity 24: is such that the ;trike it until the rear end of the ung above the top of the breechwhen this position is reached tripped by the toe 25, striking 26, and the ejector is released and s forcibly expelled. The block the opening 13 by means of 'a the head of'which is seated in a ormed for it partly in the barrely in the block. .im as my invention, and desire Letters Patent, is

eakdown gun, the combination Fame and a barrel hinged to the onthereof, and having a barrelwith a transverse opening, of a 1g actuated cartridge ejector, a ably held in said transverse openg-actuated catch pivoted at one block and transversely to said lid catch having a lip adapted to cartridge-ejector and a toe prond said barrel-rib, and a shoulder rame arranged in the path of said [11 is broken down, whereby said [drawn and the ejector released, Y as described. reakdown gun, the combination Frame and a barrel hinged to the ion thereof, and having a barrell with a transverse opening, of a ated sliding cartridge-ejector, a iably held in said opening, a catch ne end in said block and trans- ,id barrel-rib, a spring held in said cting against .said catch to carry gement with the cartridge-ejector, for withdrawing said catch from the ejector as the gun is broken down, substantially as described.

3. In a breakdown gun, the combination with a gun-frame and a barrel hinged to the front extension thereof, and having a rib on its lower side provided with a transverselyformed' opening, of a sliding spring-actuated cartridge-ejector fitted to abore formed in said barrel-rib, a block detachably held in said transverse opening and recessed through its center to form parallel opposing walls, a pivoted spring-actuated catch fitted between said parallel walls and adapted tonormally engage the cartridge-ejector, and means for disengaging the catch from the cartridge-ejector when the gun is broken down, substantially as described.

4:. In a breakdown gun, the combination with a gun-frame and-a barrel hinged to the front extension thereof, and having a rib on its lower side provided with a transverselyformed opening, of a sliding spring-actuated cartridge-ejector fitted to a bore formed in said barrel-rib, a block detachably held in said opening and recessed through its center to form parallel opposing walls, a spring-actuated catch pivoted at one end in said block and fitted between 'said parallel walls, said catch being adapted to normally engage the cartridge-ejector, a toe projecting from the opposite end of said catch beyond said barrelrib, a cavity in the front extension of the gun.- frame to receive said toe and permit a limited swinging motion to the barrel, and a shoulder in said front extension of the frame in the path of said toe when the gun is broken down, whereby the catch is withdrawn and the ejector released, substantially as described.

5. In a breakdown gun, the combination with a gun-frame and a barrel hinged to the front extension thereof, said barrel having a rib on its lower side provided with a transversely-formed opening, of a sliding springaetuated cartridge-ejector, a block fitted to the transverse opening in the barrel-rib, means for detachably holding said block in said opening, and a spring-actuated catch wholly contained in said block adapted to normally engage the cartridge ejector, and means for withdrawing said catch and releasing the cartridge-ejector when the gun is broken down, substantially as described.

Dated this 27th day of June, 1902.
